Migrate to Codex
Launching today
Bring your setup from another agent with you when you switch to Codex. Use the import flow to bring your instructions, configuration, skills, MCP servers, hooks, subagents, and recent sessions from another agent into Codex. Codex migrates the parts it can handle directly and can open a follow-up thread to help migrate anything that remains.

Codex is making switching between AI dev tools actually painless.
It lets you import your entire setup... instructions, configs, skills, MCP servers, hooks, subagents, and even recent sessions, so you don’t have to rebuild workflows from scratch.
The problem it solves is real: fragmented setups and lost context when moving between agents.
What stands out is how structured the migration is. It scans both user-level and project-level configs, creates a checklist, imports what it can, and even spins up a follow-up thread to help complete anything that doesn’t map cleanly.
Key features:
One-click import from other agents
Support for skills, MCP servers, hooks, and subagents
Migration of recent sessions into threads/projects
Guided follow-up for incomplete setup
Benefits are clear: less friction, faster onboarding, and continuity in your dev workflow.
Best suited for developers, AI teams, and anyone actively working with agent-based systems who don’t want to lose momentum during tool switches.
If you're exploring Codex or switching from another agent, this looks worth trying!
